I'll go out on a limb and put Victor Martinez first. I think you're right in the assessment that Martinez (should also play some 1st n DH) and Phillips (C and 1B) will get the most AB. Maur is basically unchallenged too but has no real experience yet so I'll put him third. Despite the best power in the quartet I have LeCroy last simply do to available ABs. That said, all 4 would be very closely bunched on my cheatsheet.
